REGISTER.

Specification of Letters Patent.

Patented May 20, 1913.

7 Application filed. April 19, 1912. Serial No. 691,866.

ing drawing, and to the figures of reference marked thereon, which forma part of this specification.

My. invention relates to improvements in i registers and has for itsobject theprovision of a. simple and inexpensive device for con--trolling the entrance of hot air into a room or auditorium.

Another object of my invention is to provide a register capable of beingconveniently and quickly installed.

Another object of my invention is to provide an arrangement foreffectively and conveniently anchoring the register in position. Anotherobject of my invention is to provide a register with relatively fewparts, 1

With these and otherobjects in view I will proceed to describe myinvention with reference to the accompanying drawings, forming a parthereof.

. There are two forms of my invention illustrated in theaccompanyingdrawings and described inthe followin specification but itwill'be evident by re erenceto the appended claims that the invention isby no 1 means limitedto the structure disclosed and that the same may bematerially modified and changes madewithout departing from the spirit orscopeof my invention.

In the drawings z-Figure 1 is a top plan view of the frame work of myregister showing the cover or controlling member removed. Fig. 2 is across section taken on the line 22, Fig. 1, with the cover in posit-ion.Fig. 3 is a top plan view in partial section of a modified form of myimproved register. Fig. 4: is a cross section taken on the line 4-4,Fig. 3.

My improved register may be used for controlling the induction of air toa room or auditorium, as well as for controlling the induction of theheat. In buildings or auditoriums which are heated by hot air, my deviceserves the purpose of both a ventilator register and heat register,since the heated air, in addition to heating the building or auditorium,serves to ventilate the same. In fact it matters not for what purpose myimproved register is used as I anticipate its adaptability to variouspurposes or uses.

The same reference characters indicate the same parts in the differentviews of the different forms.

Referring first to the form illustrated in Figs. 1 and 2, lett-henumeral 5 designate the curbing or frame for a ventilator'sha-ft orheating shaft and the numeral 6 an adjustable closure for the ventilatorshaft or heating'shaft. Those skilled in the art to which my invent-ionappertains will readily understand that the curbing or frame 5 isadaptedto be fitted into the ventilator opening, while the flange 7 7 withwhich the curbing or frame '5 is provided rests upon the floor or wallsurrounding the said opening. The frame 5 is provided with a transversebar 10, having an enlarged'central portion 12, provided with aninteriorly threaded opening 13, in which opening a screw 14 is threaded.Ihis screw 14 is attached to the closure 6 by means of a reduced part15, which is journaled in the center of the closure 6- and to thisreduced part 15 a butterfly operating member 16 is made fast on theouter side of the closure. The closure 6 is provided with a recess 17 inwhich thebutterfly operating member 16 is arranged. This closure 6 is ofsaucer shape and to the inner surface of the latter I rigidly securepins 18, which are reinforced or made fast with the closure 6 by 'meansof lugs 19, which are secured to the inner surface of the closure 6 andsurround the pins 18. The opposite or free extremities of these pins 18are adapted to pass through openings 20 formed in ears 21, arranged onthe inner periphery of the curbing 5, whereby the pins 18 serve asguides for the closure 6. The inner extremity of the screwflet isprovided with a pin 22 which passes through an opening 23, formed in theinner extremity of an inwardly projecting guide member 24:. This guidemember 24: is connected with the enlarged portion 12 of the bar *10 andextended inwardly therefrom.

Now by turning the screw 14 by means of the butterfly operating member16, the closure '6 will be moved inwardly toward the frame room orauditorium. By adjusting the screw 14, the closure 6 may be regulated toadmit the desired amount of air or heat or to close the same 011'entirely. During the adjustment of the screw 14, the closure 6 iscarried with the screw 14 and the pins 18 are caused to move in theperforations 20' of the cars 21.

Now assuming that it is desired to place my register in a concrete wallor floor. It will, of course, be impossible to pass screws through theopenings 9 in the ears 8 into the concrete for anchoring the register inposition. But in order to effectively anchor the register in position ina concrete wall or floor, I form perforations or open: ings 25 in theopposite extremities of the bar 10, andthrough these openings orperforations, I pass anchoring rods 26, which may be secured to atransverse bar 27 bridging the ventilator opening. The anchoring rods26, as shown in the drawings, are provided with hook-shaped extremities28, which pass underneath the bar 27 ,however, it must be understoodthat any other desired means may be employed for securing the anchoringrods 26 to the bar 27. In fact, it may also be possible if founddesirable to dispense with the bar 27 and anchor or secure the rods 26to some other stationary part of the building.

The form of my invention illustrated in Figs. 3 and 4 is analogous andis of much similarity to the form disclosed in Figs. 1 and 2, but thereare certain differences that exist between these two forms, which willnow be described in connection with Figs. 3 and 4. In this form of myinvention I employ a frame or curbing 29, having a flange 30 and atransverse bar 31, provided with an enlarged centrally located member32, inwhich a reduced extremity or pintle 33 of a screw 34 is journaled.The opposite extremity of this screw 34 is journaled in a top or saucershaped roof 35 by means of a reduced extremity orr pintle 36, whichpasses centrally through the roof 35. To this pintle 36 exteriorly ofthe roof 35 I fixedly se- I cure a butterfly member 37 by means of whichthe screw 34 may be turned. The

roof 35 is supported above or beyond the frame work or curbing 29 bymeans of pins 38, which pins are anchored in the frame or curbing 29 asshown at 39. The opposite extremities of these pins being secured to therim of the roof 35 as shown at 40. Between the roof 35 and the frame orcurbing, 29 It arrange a saucer shaped closure 40, which is providedwith a centrally located threaded opening 41, through which the screw 33passes. The periphery of this closure 40 is provided with a flange orextension 42, through which the pins 38 pass, whereby the closure 40 isheld against turn- 1:.-:1g '.lh,ese pins 38 also serve as guides for theclosure .40. Now assuming thatit is desired to close the registeragainst the ad mittance of air, or heat, to the room or auditoriumtheoperating member 37 of the screw 34, may be turned in the proper direction to cause the closure 40 to move toward the .frame or curbing 29,or to the a dotted line position illustrated in Fig. 4.

During the turning of the screwr34, the closure 40 will be held againstrevolving by means of the pin 38 and the screw 34 will be caused tocarry the said member to the dotted line-position. This form of myinvention may be secured in position in the wall or floor in a mannersubstantially the same as that described in connection with the form ofmyinvention illustrated in Figs. 1 and 2 inclusive, and need not bedescribed here in detail. I

From the foregoing, it is thought that the construction and manyadvantages of the herein" described invention will be apparent to thoseskilled in the art without further descriptionand it will be understoodthat various changes in the size, position and minor details ofconstruction and arrangement may be resorted to without departing fromthe spirit of my invention or sacrificing any of the advantages of thesame.

Having thus described my invention, what I claim is 1. register,comprising a frame, a closure, a screw journaled at its opposite extremities in parts of said register and connecting said closure withsaid frame, the register havinga threaded opening intermediate thejournaledextremities of said screw, the v screw passing through saidthreaded opening and cooperating with the threads of the latter when thescrew is turned for moving the closureto and from the said frame.

2. A register, comprising a frame adapted to surround the heat orventilating opening, a closure, a screw connecting said closure withsaid frame, the register having parts in which the opposite extremitiesof said screw are journaled, the register having a threaded openingintermediate the journaled extremities of said screw, the screw passingthrough the said threaded opening and cooperating with the threads ofthe latter when the screw is turned to move the closure to and from thesaid" frame, and. guide rods connecting said closure with the frame forpreventing turning of the closure.

3. A register, comprising a frame, a clesure, a screw connectlon betweensaid frame and the closure, one extremity of the said n u n screw havinga reduced extension, the frame having a centrally located member inwhich the said reduced extension of said screw is. journaled, and guiderods for said closure, the said guidercds the said closure.

P ntin tam o 4. A register, comprising a frame adapted her and guiderods for preventing turning to surround a heat or ventilating opening, aof the closure.
